Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

Optimization is one of the essential exercises for website owners and bloggers.

Without the right optimization, your content will never reach the target audience, resulting in poor conversion rates and success. One of the tasks involved with optimization is speed, and delayed page responses translate to reduced conversions.

As a website owner, you may have seen other bloggers use the term CDN here and there. If you have been wondering what CDN is and why bloggers find it useful, you are at the right place. Let’s get to know about a CDN and why you should be using it.

Understanding CDN

When a person visits your blog, they are directed to your website’s host server, which is situated somewhere in the world. This server is being accessed by every person who is currently on your website. This high traffic volume often leads to the server becoming overloaded, resulting in slow web page responses.

Users are not impressed by slow responding websites. It can cause them to become impatient and frustrated, eventually leaving the site in search of one that works better and faster. This translates to reduced conversion rates for your business. During worst-case scenarios, the host server can crash, leading to your blog becoming inaccessible.

A CDN is a great solution to prevent these problems because it is a network of servers that are spread all over the world. A CDN, which stands for Content Delivery Network, is a tool that delivers website content to users based on their geographical locations.

A good illustration by Cloudflare.


When a site implements a CDN, the static (and some dynamic) content of its website is cached and saved on these servers around the globe. The static content could be anything like javascript, CSS, images, videos, fonts, etc.

Once implemented, when a person visits the site, the CDN redirects them to the server that is closest to their geographical location.

For example, if the main server for your website is situated in California, and a user from Cape Town is trying to access it, the CDN will automatically redirect them to the nearest server, which may be located in Cape Town. The closer a user is to your host server, the more it impacts your website’s load time.

By scattering content to servers around the world, it allows your pages to load faster without applying too much pressure on the host server. The closer a user is to a CDN, the quicker your website response will be for them.

CDN has become popular in the past couple of years.

User experience plays a huge role in the success of a website, which is why it is a good idea for you to invest in a CDN.

Why does your site need a CDN?

As mentioned, CDN can significantly impact the success of a website. Without one, you could be at risk of losing potential customers. Here are some benefits.

Load the site quickly: Once CDN is implemented, web pages will open in seconds. This applies to big websites with a lot of video content as well.

Crash protection: A CDN allows you to deploy content to servers all over the world. This relieves pressure from your main host server, reducing the risks of it becoming choked or crashing.

Improved SEO: Quick responding websites often have better rankings on search engines, according to Google. CDN helps with website optimization, giving your blog an edge over the others.

Better user experience: Using CDNs can help reduce your website’s bounce rate, which is a good thing if you are looking to improve user experience. A site owner who uses CDN has also reported an increase in traffic as well as page views by individual users. This concludes that fast websites result in a more satisfying user experience.
